Answer 2

a.
`=60` miles per hour

b.
`=12` customers per day

c.
`=2.5` meters per second

d.
`=1.59` dollars per pound

Explanation:

We need to find the unit rate in each of the following.

Let us consider one by one.

a. 420 miles in 7 hours

To find the unit rate, we need to divide 420 by 7.

So, unit rate is
`(420)/(7)`

`=60` miles per hour

b. 360 customers in 30 days

To find the unit rate, we need to divide 360 by 30.

So, unit rate is
`(360)/(30)`

`=12` customers per day

c. 40 meters in 16 seconds

To find the unit rate, we need to divide 40 by 16.

So, unit rate is
`(40)/(16)`

`=2.5` meters per second

d. $7.96 for 5 pounds

To find the unit rate, we need to divide 7.96 by 5.

So, unit rate is
`(7.96)/(5)`

`=1.59` dollars per pound
